The invention relates to new substituted 4,5-diamino-1,2,4-triazol(e)-3-(thi)ones, to several processes and new intermediates for their preparation, and to their use as herbicides.

It is known that certain substituted triazolones, such as, for example, 4-amino-5-methyl-2-phenylaminocarbonyl-2,4-dihydro-3H-1,2,4-triazol-3-one, have herbicidal properties (cf. EP-A 294,666). However, the herbicidal action of this known compound is not satisfactory in all respects.

X represents oxygen or sulphur, and

Y represents oxygen or sulphur, have now been found.

Where appropriate, the compounds of the formula (I) can be present as geometric and/or optical isomers, or mixtures of isomers, of various compositions, depending on the nature of the substituents R¹, R², R³, R⁴ and R⁵. The invention claims the pure isomers as well as the mixtures of isomers.

Finally, it has been found that the new substituted 4,5-diamino-1,2,4-triazol-3-ones of the general formula (I) have interesting herbicidal properties.

Surprisingly, the substituted 4,5-diamino-1,2,4-triazol-3-ones of the general formula (I) according to the invention show a considerably more powerful herbicidal action against problem weeds than the compound 4-amino-5-methyl-2-phenylaminocarbonyl-2,4-dihydro-3H-1,2,4-triazol-3-one, which has a similar structure and profile of action.

The preparation of the Compound listed in Table 2 as Example No. 34 is described in detail below: ##STR327##

(Process (f))

2 g (32 mmol) of sodium cyanoborohydride are added at 0° C. to a mixture of 9.6 g (25 mmol) of 4-(3-chloro-benzylideneamino)-5-dimethylamino-2-(1,1-dimethyl-2-fluoro-ethylamino-carbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one and 50 ml of methanol, and the mixture is treated with saturated ethanolic hydrogen chloride solution until a methyl orange indicator changes colour. In the course of 6 hours, a further 2 g of sodium cyanoborohydride are added in portions, and the mixture is then stirred at 20° C. for 12 more hours. It is subsequently concentrated, the residue is taken up in methylene chloride, and the mixture is washed with water, dried over sodium sulphate and filtered. The filtrate is concentrated, the residue is crystallized using petroleum ether, and the product is isolated by filtration with suction.

This gives 7.9 g (82% of theory) of 4-(3-chlorobenzylamino)-5-dimethylamino-2-(1,1-dimethyl-2-fluoroethylamino-carbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 158° C.

Starting substances of the formulae (II)/(IIa): Examples (II-1) ##STR328##

130 g (1.44 mol) of carbodihydrazide are suspended in a mixture of 470 g of phenol and 200 ml of chlorobenzene, and the suspension is treated with 153 g (1.44 mol) of sodium carbonate and 3.0 g (12 mmol) of dibutyltin oxide and warmed to 50° C. to 60° C. in a water pump vacuum. A solution of 247 g (1.44 mol) of tetramethylchloroformamidiniumchloride in 400 g of phenol is added dropwise in the course of 20 minutes, during which process water distils off. Chlorobenzene is then distilled off in a water pump vacuum until the boiling point of phenol is reached. The reaction mixture is subsequently heated to 160° C. to 180° C. under atmospheric pressure, during which process dimethylamine is eliminated. After 3 hours, phenol is distilled off at 190° C. for one hour. The solid residue which remains is extracted in a Soxleth extractor using 1.5 liters of isopropanol; the isopropanol solution is evaporated.

This gives 47 g (23% of theory) of 4-amino-5-dimethylamino-2,4-dihydro-3H-1,2,4-triazol-3-one as a crystalline residue of melting point 205° C.

EXAMPLE (II-2) ##STR329##

A mixture of 360 g (2.0 mol) of carbodihydrazide, 212 g (2.0 mol) of sodium carbonate and 580 g of phenol is heated to 50° C. to 60° C. A solution of 314 g (2.0 mol) of trimethyl-chloroformamidine hydrochloride in 314 g of phenol is then added dropwise in a water pump vacuum in the course of 30 minutes. The reaction mixture is then stirred for 60 minutes at 50° C. to 60° C. and subsequently heated to 190 ° C., during which process dimethylamine is eliminated. When the evolution of gas has ceased, the phenol is distilled off in a water pump vacuum and the residue is recrystallized from water.

This gives 60 g (26% of theory) of 4-amino-5-methylamino-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 220° C.

EXAMPLE (II-3) ##STR330##

Step 1 ##STR331##

856 g (4.0 mol) of diphenyl carbonate are initially introduced into the reaction vessel with water cooling, and 245 g (4.0 mol) of N,N-dimethylhydrazine are added dropwise. The mixture is then slowly heated to 60° C. (in the course of 4 hours). The mixture is cooled to 20° C., and 200 g (4.0 mol) of hydrazine hydrate are subsequently added, and the reaction mixture is stirred for 12 hours at 20° C. After the mixture has been heated to 70° C. to 80° C. for one hour, volatile components are distilled off under a water pump vacuum until a bottom temperature of 100° C. is reached. The residue which remains essentially contains a solution of 1,1-dimethylcarbodihydrazide in phenol, and this solution is employed directly in the next step.

Step 2 ##STR332##

251 g of the above solution of 1,1-dimethylcarbodihydrazide in phenol (about 0.82 mol) are diluted with 100 g of phenol, 87 g (0.82 mol) of sodium carbonate are added, and the mixture is heated to 50° C. to 60° C. A solution of 140 g (0.82 mol) of tetramethyl-chloroformamidinium chloride in 250 g of phenol is then added dropwise in the course of 75 minutes in an oil-pump vacuum. The reaction mixture is then refluxed for 6 hours under atmospheric pressure (about 190° C. to 195° C.), during which process dimethylamine is eliminated. The mixture is then distilled under an oil-pump vacuum, and the distillate is redistilled. The distillate which has now been obtained (40 g) is taken up in xylene and the mixture is cooled to -78° C. The product which is obtained in crystalline form in this process is isolated by filtration with suction.

This gives 22.8 g (16% of theory) of 4,5-bis-dimethylamino-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 93° C.

Example (II-4) ##STR333##

Step 1 ##STR334##

A solution of 94 g (2.0 mol) of methylhydrazine in 100 ml of methanol is cooled to 0° C. to -20° C., and 268 g (2.0 mol) of dimethyl pyrocarbonate are continuously added dropwise in such a way that the temperature does not exceed 0° C. The reaction mixture is then stirred at 80° C. until the evolution of gas has virtually ceased, and subsequently distilled under a water pump vacuum.

This gives 181 g (87% of theory) of N-methyl-n-methoxycarbonylhydrazine of boiling point 65° C./15 torr.

Step 2 ##STR335##

624 g (6.0 mol) of 1-methyl-1-methoxycarbonylhydrazine and 334 g (3.15 mol) of sodium carbonate are initially introduced into 2 liters of ethylene chloride, and 939 g (6.0 mol) of phenyl chloroformate are added dropwise with stirring in such a way that the temperature does not exceed 20° C. The mixture is then stirred for another 60 minutes at 60° C., and the sodium chloride which has been liberated is separated off by filtration with suction. The solvent is removed from the filtrate by distillation under a water pump vacuum at a bottom temperature of not more than 110° C.

This gives 1285 g (96% of theory) of 1-methyl-1-methoxycarbonyl-2-phenoxycarbonyl-hydrazine as an oily residue which gradually crystallizes.

Melting point: 86° C.

Step 3: ##STR336##

206 g (4.12 mol) of hydrazine hydrate are initially introduced into a reaction vessel at 20° C., and a solution of 922 g (4.12 mol) of 1-methyl-1-methoxycarbonyl-2-phenoxycarbonyl-hydrazine in 600 g of chlorobenzene, warmed to 40° C., is added all at once, which causes the temperature of the reaction mixture to rise to about 60° C. The mixture is then stirred for 4 hours at 80° C. and subsequently concentrated under water pump vacuum until a bottom temperature of about 100° C. is reached. The residue, which essentially contains 1-methyl-1-methoxy-carbonyl-carbodihydrazide, is employed directly in the next step.

Step 4 ##STR337##

A mixture of 160 g (0.626 mol) of 1-methyl-1-methoxycarbonyl-carbodihydrazide and 160 g of phenol is warmed to 40° C., and 142 g (0.626 mol) of diphenyl methyliminocarbonate are added. When the exothermic reaction has subsided, the mixture is slowly heated to 150° C. under a water pump vacuum, during which process about 150 g of phenol distil off. After cooling, the residue is stirred with 100 ml of water and 120 g of 50% strength sodium hydroxide solution, and the mixture is refluxed for 60 minutes. 300 ml of 18% strength hydrochloric acid are then added and the batch is evaporated. The residue is distilled under an oil-pump vacuum and the crude distillate is redistilled.

This gives 45 g (50% of theory) of 4,5-bis-methylamino-2,4-dihydro-3H-1,2,4-triazol-3-one as an oily product which solidifies in the receiving vessel to a wax-like substance. Stirring with ethyl acetate gives 40 g (44%) of a white, crystalline product of melting point 135-137° C.

EXAMPLE (II-5) ##STR338##

A phenolic solution of 1-methyl-1-methoxycarbonyl-carbodihydrazide is prepared as described in Example (II-4), step 3. 384 g of this solution (1.5 mol) are taken up in 200 ml of chlorobenzene, 239 g (2.25 mol) of sodium carbonate are added, and the mixture is warmed to 50° C. under a water pump vacuum. During this process, a solution of 244 g (1.5 mol) of dichloromethylenedimethylimmonium chloride in 566 g of phenol is added dropwise, during which process water is removed by azeotropic distillation. Stirring of the reaction mixture is then continued for 60 minutes at 120° C. under atmospheric pressure, and the mixture is then hot-filtered and washed with ethanol and acetone. The organic solution is concentrated, the residue is refluxed with 240 ml of 50% strength sodium hydroxide solution, allowed to cool, and rendered neutral using concentrated hydrochloric acid. After the mixture has been concentrated under a water pump vacuum, the residue is distilled under an oil-pump vacuum, and the crude distillate is redistilled.

This gives 72 g of oily product (boiling point 165° C./1 mbar) which is converted into a pure crystalline product using 300 ml of toluene.

Yield: 60.0 g (25.5% of theory) of 4-methylamino5-dimethylamino-2,4-dihydro-3H-1,2,4-triazol-3-one; Melting point: 129° C.

EXAMPLE (II-6) ##STR339##

A mixture of 58 g (0.25 mol) of 1,3-diamino-2-methylguanidine hydroiodide, 53.5 g (0.25 mol ) of diphenyl carbonate and 20 g of phenol is heated to 160° C. while stirring, until the mixture is virtually homogeneous. 34.5 g (0.25 mol) of potassium carbonate are then added in portions, during which process carbon dioxide is liberated. After 60 minutes at 160° C., the mixture is slightly cooled, and the phenol is distilled off under a water pump vacuum. The residue is taken up in 200 ml of water, the mixture is rendered neutral using hydrochloric acid, and ethanol is added slowly, during which process the reaction mixture is obtained in crystalline form.

This gives 24 g (74% of theory) of 4-amino-5-methylamino-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 214° C.

STARTING SUBSTANCES OF THE FORMULA (VIII) EXAMPLE (VIII-1) ##STR364##

3.7 g (0.02 mol) of 4-ethoxymethyleneamino-5-methylamino-2,4-dihydro-3H-1,2,4-triazol-3-one are dissolved in 100 ml of acetonitrile, and 100 mg of diazabicycloundecene (DBU) and 2.8 g (0.02 mol) of chloro-tert-butyl isocyanate are added in succession. The mixture is stirred for 12 hours at 20° C. and then concentrated. The residue is taken up in methylene chloride, and the mixture is washed with water, dried over sodium sulphate and filtered. The solvent is removed from the filtrate by distillation under a water pump vacuum, and the residue is crystallized by trituration with diethyl ether.

This gives 5.2 g (82% of theory) of 2-chloro-tert-butylaminocarbonyl-4-ethoxymethyleneamino-5-methyl-amino-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 142° C.

INTERMEDIATES OF THE FORMULA (XXI) EXAMPLE (XXI-1) ##STR366##

12.9 g (0.1 mol) of 4-amino-5-methylamino-2,4-dihydro-3H-1,2,4-triazol-3-one are refluxed on a water separator with 150 ml of methyl isobutyl ketone and mg of p-toluenesulphonic acid until virtually no water is separated any longer (about 2 hours). The mixture is filtered, the filtrate is concentrated, and the residue is triturated with petroleum ether.

EXAMPLE A

Pre-emergence test

Solvent: 5 parts by weight of acetone

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To prepare a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added, and the concentrate is diluted with water to the desired concentration.

Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of active compound. It is expedient here to keep constant the amount of water per unit area. The concentration of active compound in the preparation is of no importance, only the application rate of the active compound per unit area being decisive. After three weeks, the degree of damage to the plants is rated in % damage in comparison with the development of the untreated control. The figures denote:

0%=no action (like untreated control)

100%=total destruction

In this test, a clearly superior activity compared with the comparison substance (A) is shown, for example, by the compounds Preparation Examples 16, 17, 18 and 19.
